Abstract
A reticular needlework fabric (10, 16) comprising a unitarily molded network of strands (12). The network has a plurality of spaced strands (12) extending parallel to a first axis, and a plurality of spaced strands (12) extending parallel to a second axis. A selected number of marker strands (14) are included among the strands (12) parallel to at least one axis. The marker strands (14) are separated from each other by a selected number of strands (12) and have molded-in features rendering them visually distinguishable from the remaining strands (12). The method of the invention for making such a reticular needlework fabric (10, 16) formed by channels (22) formed in at least one of the opposed faces (20) of a two-part mold (17) includes the steps of altering selected marker strand channels (24) so as to produce molded-in features in the marker strands (14) molded therein, rendering them visually distinguishable from the remaining strands (12). Additional steps include closing the mold (17), filling the mold with selected molten plastic, cooling the plastic sufficiently to solidify it, and opening the mold (17) and removing the needlework fabric (10, 16) therefrom.
